Aleksandr Efimov reassigned IMPALA-15339:
-----------------------------------------
Assignee: Aleksandr Efimov
> Calcite planner: RexLiteralConverter has no case for REAL or BINARY
> -------------------------------------------------------------------
>
> Key: IMPALA-15339
> URL: https://issues.apache.org/jira/browse/IMPALA-15339
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Aleksandr Efimov
> Assignee: Aleksandr Efimov
> Priority: Major
>
> {code}
> set planner=calcite;
> select cast(1.5 as real);
> AnalysisException: java.lang.IllegalStateException: Unsupported RexLiteral:
> DOUBLE
> select x'616263';
> AnalysisException: java.lang.IllegalStateException: Unsupported RexLiteral:
> BINARY
> {code}
> The first is ordinary Impala SQL - the original planner answers 1.5. Both
> types are
> mapped in both directions by ImpalaTypeConverter and the row type is derived
> before
> this point, so the plan stops where the literal has to become an Impala
> expression.
> The message names DOUBLE for a REAL literal because it prints the literal's
> own type
> name rather than the type the switch is on, so it points at a case that is
> present.
> Behind the BINARY case is the double conversion of IMPALA-15338, in a second
> type.
> Calcite folds a projection of constants into a VALUES row, and ImpalaValuesRel
> re-creates each literal from its text - which bytes that are not valid UTF-8
> do not
> have: "non-utf8 string: unhex(\"FF00FE\")".
